Kev piav qhia txog khoom

Cov hlau/kauv kub-kub los ntawm kev ua tiav cov hlau kub kawg los ntawm kev txias laminar mus rau qhov kub teem, uas muaj cov kauj cua, kauj hlau tom qab txias, raws li qhov xav tau sib txawv ntawm cov neeg siv, nrog cov kab tiav sib txawv (tiaj tus, ncaj, txiav transverse lossis longitudinal, tshuaj xyuas, hnyav, ntim khoom thiab logo, thiab lwm yam) thiab dhau los ua cov hlau phaj, tiaj tus yob thiab txiav longitudinal hlau. Vim tias cov khoom hlau kub-kub muaj lub zog siab, zoo toughness, yooj yim ua thiab weldability zoo thiab lwm yam zoo heev, nws yog dav siv hauv kev tsim nkoj, tsheb, choj, kev tsim kho, tshuab, lub thawv siab thiab lwm yam kev lag luam tsim khoom.

Cov yam ntxwv ntawm cov khoom

Cov hlau carbon yog ib hom hlau uas feem ntau yog ua los ntawm hlau thiab carbon. Nws muaj cov pa roj carbon ntau dua, qhov kub yaj qis dua thiab ruaj khov dua piv rau cov hlau tsis xeb.

Cov hlau carbon yog cov khoom siv engineering thiab kev tsim kho uas siv dav tshaj plaws rau kev siv hauv kev lag luam ntawm qhov loj, suav nrog cov qauv marine, cov chaw tsim hluav taws xob, kev thauj mus los, kev ua tshuaj lom neeg thiab kev tsim roj av thiab kev ua kom huv.

Cov kev ceev faj

Δ Cov khoom siv kub dov yog annealing hauv lub cub tawg txias dov thiab tom qab pickling hauv acid.

Δ Txhua lub zeb yob raug sib tsoo rau ntawm lub tshuab sib tsoo precision nrog kev chamfering kom raug tom qab ua haujlwm thawj zaug.

Δ Txhua daim ntawv raug khaws cia rau hauv cov thoob dej sib txawv thiab cov ntawv raug ziab rau ntawm lub tshuab txhuam ua ntej xa tawm.

Δ Cov ntawv no rov ua kom sov dua ces xa mus rau lub tshuab ncaj rau kev ncaj thiab pickling hauv cov kua qaub thiab xa mus rau kev ntim khoom raws li qhov loj me thiab zoo.

Δ Kev tshuaj xyuas tau ua tiav ntawm ntau theem. Los ntawm cov neeg ua haujlwm paub dhau los tswj hwm cov txheej txheem sab hauv kom zoo los ntawm kev dov, annealing, pickling, kev kho cov khib nyiab thiab lwm yam.
